YUXI’s MMO disc anode is generally used in impressed current cathodic protection system for ship hulls. Surrounded by a dielectric shield to distribute the current evenly across the ship’s hull, it is suitable for use in fresh, brackish, and seawater environments.
The current emitting face of the disc anode is made from titanium substrate coated with a mixed metal oxide catalyst. When applied on titanium, the mixed metal oxide coating has an extremely low consumption rate, measured in terms of milligrams per year. Direct current transfer is accomplished through the mixed metal oxide catalyst which is highly conductive, so that higher current outputs are achievable. As a result, the dimensions of disc anodes remain nearly constant throughout the design life.
Shaped as a circular flat plate, this slim disc anode fits flush with the hull surface, minimizing the drag resistance and maintaining the flow dynamics during voyages. Its low profile also avoids the problem of rubbing by anchor chains.
The titanium substrate of the anode is selected according to ASTM B265 Grade 1 standard requirements. The high purity titanium has proven excellent chemical corrosion resistance as well as low electrical resistance.
Based upon accelerated life testing conducted by an independent laboratory, our MMO coating has been proven to be superior to other similar products in the market.
* Depend on the form of usage, we can produce anodes with different nobel metal oxide ratios and differing coating thickness.
The anode is sealed with water-proof epoxy resin to avoid any leaks.
The disc anode comes with internal bolting for recessed installation on the ship’s hull. And it can be easily changed by a diver with the assistance of a shipboard technician.
